Hey,

I should start off by saying that I am looking at maybe getting a V36. I wanted to ask any V36 owners out there, who have been on a dyno how much power you guys are making?

And if any one has done any modifications ( catback exhaust, intake etc) or tuning (UpRev), how much difference did it make?

I apologise in advance if there is already a thread like this, please post a link to the thread if possible

Thankyou

I bought my auto V35 350GT coupe from a specialist importer. Compared to all the others I test drove, mine seems to have a noticeable advantage in acceleration over the others.

The car was auction grade 4, other than a grounding kit, tein coilovers with EDFC and the factory powerduct (with K&N panel filter), the car is stock. There seems to be very touchy throttle response, particularly at low rpm. I cannot find out what could be generating the extra power! The dealer seemed to think it was chipped. I checked behind the passengers side panel, and the ECU is stock. Would there be any other way to see if it is chipped?

A friend seems to think it may even have upgraded cams- apparently this is pretty common in Japan as it gives them a bit more low down power and torque.

By comparison, I drove one (not from the importer, but someone who was selling privately) with a kinetix plenum, stillen induction and performance exhaust, and I think mine would leave it in the dust.

I haven't done a standing 0-100 yet, nor had it dyno tested.

Yeah I did a bit of research into grounding kits, and apparently they do wonders, particularly for autos. The thread I found was for a us website, I think it was g35driver.com

Someone asked if they actually do anything and the responses were all overwhelmingly positive.

Still, great car, ant it'll run rings around my old R34

I'm still yet know a person who has installed a grounding kit and had any impact outside auto shift firmness and placebo.

Placebo is a very powerful thing.. I read many many posts about people claiming Strut tower braces had 'significantly reduced' bodyroll. which a STB cannot possibly do.

Grounding kits work for auto boxes due to the bad factory grounding. It helps shift smoother and abit harder. Another thing I noticed was my audio got a tad louder. The guys down at the audio shop said it was the grounding that made it better. Who knows...As to gaining kW....I doubt it.

I dont think it makes it look messy....then again I made sure I hid the wires where I could...looks pretty much stock.

I wouldn't say its in my head, as I didn't know it had a grounding kit until after I bought it.

But it definitely had a definite power advantage over the others I drove, like I said- is there a way I can tell if it is chipped or has aftermarket cams

I think the general sentament is the difference is not the grounding kit. something else has been done to it.. possibly a throttle controller installed which has changed the throttle body response vs pedal position. Could also have had a uprev tune, which uses the stock ECU.

Grounding kits will normally only help if you factory grounds are very poorly designed, or corroded/damaged. The extra grounding from the transmission casing to the engine/battery may help as the auto solenoids probably ground to the transmission casing, and the existing grounds are a source of voltage drop.

Did it accelerate better at full throttle, or did you just notice the throttle pedal response was different?

    • Hi GTSBoy, Excuse my ignorance but what does a "Bad" Knee point mean ? 
    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
